Achromatic vector vortex beams from a glass cone

Under total internal reflection light acquires a phase shift that depends on its polarisation. Here, the authors show that this effect can be harnessed to generate so-called vector vortex beams—light with polarization and phase singularities—when white light is back-reflected from a glass cone
